Plastic container

Abstract

A plastic container, especially an ampoule, a bottle or the like, has a container neck on which a plug device, particularly a needle holder, can be mounted. The plug device is held on the container, without a special ring or the like, by a holder formed as a unitary part of the container. The holder forms a bayonette connection with a mating part on the plug device.

What is claimed is: 
     
       1. A container, comprising: a body;   a neck extending from said body along a container axis; and   holder means, formed as a unitary portion of the container, for releasably coupling said neck to a plug device, said holder means forming one part of a bayonette connection between said neck and the plug device and including first and second holder walls on opposite exterior sides of said neck, each of said holder walls extending substantially parallel to said container axis and having a holding catch on a front portion thereof facing said neck, such said holding catch having a stop surface limiting relative rotation between said holding catches and the plug device.   
     
     
       2. A container according to claim 1 wherein each said holding catch extends peripherally about said neck through an arc not greater than about 90° and spaced from said neck, said stop surfaces being located at ends of said holding catches. 
     
     
       3. A container according to claim 2 wherein each said holding catch comprises a spiral contact surface and a planar contact surface oriented generally perpendicularly to said container axis forming the bayonette connection between said neck and the plug device. 
     
     
       4. A container according to claim 3 wherein said body and neck are formed of plastic, and said holder means are formed as a unitary one-piece member with said neck and said body without seams and welding. 
     
     
       5. A container according to claim 2 wherein said body and neck are formed of plastic, and said holder means are formed as a unitary one-piece member with said neck and said body without seams and welding. 
     
     
       6. A container according to claim 1 wherein said body and neck are formed of plastic, and said holder means are formed as a unitary one-piece member with said neck and said body without seams and welding. 
     
     
       7. A container according to claim 1 wherein a plug device is coupled to said neck, said plug device having a laterally extending flange engaging said holding catches to form the bayonette connection therebetween.
